Circuit Express vs Bluefruit

Post by NDB »

Hi, attempting to build the UV Parasol and unfortunately Circuit Playground Express is out of stock. Will Circuit Playground Bluefruit be a 1-for-1 swap?

Lithium Ion Cylindrical Battery - 3.7v 2200mAh is also out of stock. Can I use Lithium Ion Battery Pack - 3.7V 4400mAh?

Thank you

In general yes, but for that project (https://learn.adafruit.com/personal-bla ... uv-parasol, correct?) it will not since there is no MakeCode support. However, the code just turns on the NeoPixels and could be rewritten in CircuitPython.

As for the battery, yes. All LiPos are 3.7v, bigger ones (in terms of their mAh rating) will last longer. So using a 4400mAh one will last roughly twice as long as a 2200mAh one.

Thank you dastels! Yes, you have the right project. Not familiar with Circuit Python...reading the intro by Kattni Rembor to get up to speed.

dastels, if I used the Circuit Playground Classic would that be better (meaning works like Playground Express but I don't have to code it Like Payground Bluefruit)

The CircuitPlayground Classic is only programmable in C++/Arduino; there is no MakeCode or CircuitPython support. That said, it should be able to do the job. It needs close to 400 bytes to drive that number LEDs, but the MCU has 2048 bytes and the code shouldn't use much so there should be room.
